2012-09-14vfs: make O_PATH file descriptors usable for 'fstat()'Linus Torvalds1-1/+1
We already use them for openat() and friends, but fstat() also wants to be able to use O_PATH file descriptors. This should make it more directly comparable to the O_SEARCH of Solaris. Note that you could already do the same thing with "fstatat()" and an empty path, but just doing "fstat()" directly is simpler and faster, so there is no reason not to just allow it directly. See also commit 332a2e1244bd, which did the same thing for fchdir, for the same reasons.

2012-09-14eCryptfs: Copy up attributes of the lower target inode after renameTyler Hicks1-0/+5
After calling into the lower filesystem to do a rename, the lower target inode's attributes were not copied up to the eCryptfs target inode. This resulted in the eCryptfs target inode staying around, rather than being evicted, because i_nlink was not updated for the eCryptfs inode. This also meant that eCryptfs didn't do the final iput() on the lower target inode so it stayed around, as well. This would result in a failure to free up space occupied by the target file in the rename() operation. Both target inodes would eventually be evicted when the eCryptfs filesystem was unmounted. This patch calls fsstack_copy_attr_all() after the lower filesystem does its ->rename() so that important inode attributes, such as i_nlink, are updated at the eCryptfs layer. ecryptfs_evict_inode() is now called and eCryptfs can drop its final reference on the lower inode. http://launchpad.net/bugs/561129 Signed-off-by: Tyler Hicks <[email protected]> Tested-by: Colin Ian King <[email protected]> Cc: <[email protected]> [2.6.39+]
2012-09-14eCryptfs: Call lower ->flush() from ecryptfs_flush()Tyler Hicks1-2/+8
Since eCryptfs only calls fput() on the lower file in ecryptfs_release(), eCryptfs should call the lower filesystem's ->flush() from ecryptfs_flush(). If the lower filesystem implements ->flush(), then eCryptfs should try to flush out any dirty pages prior to calling the lower ->flush(). If the lower filesystem does not implement ->flush(), then eCryptfs has no need to do anything in ecryptfs_flush() since dirty pages are now written out to the lower filesystem in ecryptfs_release().

2012-09-14eCryptfs: Write out all dirty pages just before releasing the lower fileTyler Hicks1-0/+1
Fixes a regression caused by: 821f749 eCryptfs: Revert to a writethrough cache model That patch reverted some code (specifically, 32001d6f) that was necessary to properly handle open() -> mmap() -> close() -> dirty pages -> munmap(), because the lower file could be closed before the dirty pages are written out. Rather than reapplying 32001d6f, this approach is a better way of ensuring that the lower file is still open in order to handle writing out the dirty pages. It is called from ecryptfs_release(), while we have a lock on the lower file pointer, just before the lower file gets the final fput() and we overwrite the pointer. https://launchpad.net/bugs/1047261 Signed-off-by: Tyler Hicks <[email protected]> Reported-by: Artemy Tregubenko <[email protected]> Tested-by: Artemy Tregubenko <[email protected]> Tested-by: Colin Ian King <[email protected]>
2012-09-14MIPS: Malta: Remove RTC Data Mode bootstrap breakageMaciej W. Rozycki1-5/+0
YAMON requires and enforces the RTC Data Mode (Register B, DM bit) to binary, that is the bit is set every time the board goes through the firmware bootstrap sequence. Likewise its calendar manipulation commands interpret or set the RTC registers unconditionally as binary, never actually checking what the value of the DM bit is, under the (correct) assumption that it has been previously set, to indicate the binary mode. A change to Linux a while ago however introduced a platform-specific tweak that clears that bit and therefore forces the data mode to BCD. This causes clock corruption and misinterpretation that has to be fixed up by user-mode tools in system startup scripts as the initial clock is often incorrect according to the BCD interpretation forced. This change removes the hack; a comment included refers to alarm code, but even if it was broken at one point by requiring the BCD mode, it should have been trivially corrected and even if not, given how rarely the alarm feature is used, that was not really a reasonable justification to break the system clock that is indeed used by virtually everything. And either way the alarm code has been since fixed anyway. Signed-off-by: Maciej W.

2012-09-14[SCSI] scsi: virtio-scsi: Fix address translation failure of HighMem pages ↵Wang Sen1-1/+1
used by sg list When using the commands below to write some data to a virtio-scsi LUN of the QEMU guest(32-bit) with 1G physical memory(qemu -m 1024), the qemu will crash. # sudo mkfs.ext4 /dev/sdb (/dev/sdb is the virtio-scsi LUN.) # sudo mount /dev/sdb /mnt # dd if=/dev/zero of=/mnt/file bs=1M count=1024 In current implementation, sg_set_buf is called to add buffers to sg list which is put into the virtqueue eventually. But if there are some HighMem pages in table->sgl you can not get virtual address by sg_virt. So, sg_virt(sg_elem) may return NULL value. This will cause QEMU exit when virtqueue_map_sg is called in QEMU because an invalid GPA is passed by virtqueue. Two solutions are discussed here: http://lkml.indiana.edu/hypermail/linux/kernel/1207.3/00675.html Finally, value assignment approach was adopted because: Value assignment creates a well-formed scatterlist, because the termination marker in source sg_list has been set in blk_rq_map_sg(). The last entry of the source sg_list is just copied to the the last entry in destination list. Note that, for now, virtio_ring does not care about the form of the scatterlist and simply processes the first out_num + in_num consecutive elements of the sg[] array. I have tested the patch on my workstation. QEMU would not crash any more.

2012-09-13mlx4_core: Fix integer overflows so 8TBs of memory registration worksYishai Hadas2-17/+23
This patch adds on the fixes done in commits 89dd86db78e0 ("mlx4_core: Allow large mlx4_buddy bitmaps") and 3de819e6b642 ("mlx4_core: Fix integer overflow issues around MTT table") so that memory registration of up to 8TB (log_num_mtt=31) finally works. It fixes integer overflows in a few mlx4_table_yyy routines in icm.c by using a u64 intermediate variable, and int/uint issues that caused table indexes to become nagive by setting some variables to be u32 instead of int.

2012-09-14ACPI / PM: Infer parent power state from child if unknown, v2Rafael J. Wysocki1-0/+10
It turns out that there are ACPI BIOSes defining device objects with _PSx and without either _PSC or _PRx. For devices corresponding to those ACPI objetcs __acpi_bus_get_power() returns ACPI_STATE_UNKNOWN and their initial power states are regarded as unknown as a result. If such a device is a parent of another power-manageable device, the child cannot be put into a low-power state through ACPI, because __acpi_bus_set_power() refuses to change power states of devices whose parents' power states are unknown. To work around this problem, observe that the ACPI power state of a device cannot be higher-power (lower-number) than the power state of its parent. Thus, if the device's _PSC method or the configuration of its power resources indicates that the device is in D0, the device's parent has to be in D0 as well. Consequently, if the parent's power state is unknown when we've just learned that its child's power state is D0, we can safely set the parent's power.state field to ACPI_STATE_D0.

2012-09-13bnx2x: prevent timeouts when using PFCYaniv Rosner1-3/+5
Prevent updating the xmac PFC configuration when using a link speed slower than 10G -the umac block is responsible for 1G or slower connections, therefore it is possible the xmac block is reset when connection is slower.

2012-09-13bnx2x: fix stats copying logicYuval Mintz1-2/+5
FW needs the driver statistics for management. Current logic is broken in that the function that gathers the port statistics does not copy its own statistics to a place where the FW can use it. This patch causes every function that can pass statistics to the FW to do so.

2012-09-13bnx2x: Avoid sending multiple statistics queriesDmitry Kravkov1-3/+5
During traffic when DCB is enabled, it is possible for multiple instances of statistics queries to be sent to the chip - this may cause the FW to assert. This patch prevents the sending of an additional instance of statistics query while the previous query hasn't completed.

2012-09-13drm/radeon: make 64bit fences more robust v3Christian König1-3/+5
Only increase the higher 32bits if we really detect a wrap around. v2: instead of increasing the higher 32bits just use the higher 32bits from the last emitted fence. v3: also use last emitted fence value as upper limit. The intention of this patch is to make fences as robust as they where before introducing 64bit fences. This is necessary because on older systems it looks like the fence value gets corrupted on initialization. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=51344 Should also fix: https://bugs.freedesktop.org/show_bug.cgi?id=54129 https://bugs.freedesktop.org/show_bug.cgi?id=54662 https://bugzilla.redhat.com/show_bug.cgi?id=846505 https://bugzilla.redhat.com/show_bug.cgi?id=845639 3.5 needs a separate patch due to changes in the fence code. Will send that out separately. Signed-off-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2012-09-13drm/radeon: rework pll selection (v3)Alex Deucher1-34/+129
For DP we can use the same PPLL for all active DP encoders. Take advantage of that to prevent cases where we may end up sharing a PPLL between DP and non-DP which won't work. Also clean up the code a bit. v2: - fix missing pll_id assignment in crtc init v3: - fix DP PPLL check - document functions - break in main encoder search loop after matching. no need to keep checking additional encoders. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=54471 Signed-off-by: Alex Deucher <[email protected]> Cc: [email protected]
2012-09-13net: qmi_wwan: call subdriver with control intf onlyBjørn Mork1-3/+4
This fixes a hang on suspend due to calling wdm_suspend on the unregistered data interface. The hang should have been a NULL pointer reference had it not been for a logic error in the cdc_wdm code. commit 230718bd net: qmi_wwan: bind to both control and data interface changed qmi_wwan to use cdc_wdm as a subdriver for devices with a two-interface QMI/wwan function. The commit failed to update qmi_wwan_suspend and qmi_wwan_resume, which were written to handle either a single combined interface function, or no subdriver at all. The result was that we called into the subdriver both when the control interface was suspended and when the data interface was suspended. Calling the subdriver suspend function with an unregistered interface is not supported and will make the subdriver bug out. Signed-off-by: Bjørn Mork <[email protected]> Signed-off-by: David S.

2012-09-13net_sched: gred: actually perform idling in WRED modeDavid Ward1-11/+15
gred_dequeue() and gred_drop() do not seem to get called when the queue is empty, meaning that we never start idling while in WRED mode. And since qidlestart is not stored by gred_store_wred_set(), we would never stop idling while in WRED mode if we ever started. This messes up the average queue size calculation that influences packet marking/dropping behavior. Now, we start WRED mode idling as we are removing the last packet from the queue. Also we now actually stop WRED mode idling when we are enqueuing a packet.

2012-09-13net_sched: gred: fix qave reporting via netlinkDavid Ward1-1/+4
q->vars.qavg is a Wlog scaled value, but q->backlog is not. In order to pass q->vars.qavg as the backlog value, we need to un-scale it. Additionally, the qave value returned via netlink should not be Wlog scaled, so we need to un-scale the result of red_calc_qavg(). This caused artificially high values for "Average Queue" to be shown by 'tc -s -d qdisc', but did not affect the actual operation of GRED.

2012-09-13mISDN: Fix wrong usage of flush_work_sync while holding locksKarsten Keil7-11/+15
It is a bad idea to hold a spinlock and call flush_work_sync. Move the workqueue cleanup outside the spinlock and use cancel_work_sync, on closing the channel this seems to be the more correct function. Remove the never used and constant return value of mISDN_freebchannel. Signed-off-by: Karsten Keil <[email protected]> Cc: <[email protected]> Signed-off-by: David S. Miller <[email protected]>
